Product details

The CaliMar CMARCAP42-2Y is a replacement salt cell built to fit AutoPilot chlorine generator systems, specifically the RC-42, SC-48 and PPC3. It carries a 50,000 gallon rating.

When a cell needs replacing

Salt cells wear out. The plates lose their coating over years of service, output falls, and the pool runs short on chlorine even with the controller turned up. Once cleaning the cell no longer brings output back, the cell itself is the part to change.

What you keep

Only the cell is replaced here. The AutoPilot power center, the plumbing and the wiring all stay in place, which makes this a straightforward swap rather than a system change.

Check the model first

Confirm your system is an RC-42, SC-48 or PPC3 before ordering, and confirm your pool is within the 50,000 gallon rating. Matching the part number CMARCAP42-2Y is the surest way to get the right capacity.
